Subject: hpfs: remove ->writepage
Date: Fri, 2 Dec 2022 11:26:42 +0100
->writepage is a very inefficient method to write back data, and only
used through write_cache_pages or a a fallback when no ->migrate_folio
method is present.
Set ->migrate_folio to the generic buffer_head based helper, and remove
the ->writepage implementation.
